Thanks. The Nitecore NU20 CRI looks good, but I’m concerned the spot beam might be too intense for close work. The NU25 is pretty interesting, but probably overly complicated as he would only really need the auxiliary light.
The Nitecore NU10 CRI looks good, I’m just not sure whether 115 lumens is enough.
Thanks. The LiitoKala charger is a good idea. I have a spare Li-200 to give him if I don’t get something with built-in charging.
That Boruit looks interesting, but I’m not sure about the colour temperature, UI and overall quality. Ideally I’d like to get something simple, high quality and tough.
I wouldnt recommend 18350 or 18650. Capacity to weight ratio is not so good. Usually more easy to carry extra 4xAA cells neither lithium charger.
I think you need to choose between AA and new nitecores with integrated li-pol. Both preferable with plastic bodies.
Something from Fenix?
